Can't open a Morphic world

[tinchodias]

I suspect this should be done via BlMorphicWorldEmbeddingElement class>>#open or openMain but DNU is obtained.

Problems in the method BlMorphicWorldMorph>>#beMain

• Nonexistent method: Cursor class >> currentCursor:
• Nonexistent global variable: ActiveHand

Another related:

The method BlMorphicWorldState>>#assuredCanvas sends self canvas and self canvas: ... and they are not implemented in the hierarchy.

It's strange that its sibling AthensWorldState has #doDeferredUpdatingFor: with same problem: a self canvas: ... that is not implemented in the hierarchy. So this is not isolated to Bloc "WorldState" but also to the Athens one.

Another one, related too:

The BlocHost-Morphic package extends PharoCommonTools with a method that references an nonexistent class Transcripter:

emergencyDebugger
	^ tools
		at: #emergencyDebugger
		ifAbsent: [ Transcripter ]

[tinchodias]

Sub-issues:

• Undeclared global reference to Trasncripter in BlocHost-Morphic extension to PharoCommonTools #141
• Unimplemented self-send of #canvas in BlMorphicWorldState>>#assuredCanvas #142

There are several unimplemented methods:

Probably they were added in superclass while this code was unmaintained

This capture shows the fragility of this piece of code... setting the value of a Morphic global using instVarAt:put:.

After asking @plantec (some time ago) and @tesonep we are proceeding to remove this host.
